AP BIOLOGY

Detailed explanation-1: -Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity.

Detailed explanation-2: -The majority of the respiratory tree, from the nasal cavity to the bronchi, is lined by pseudostratified columnar ciliated epithelium.

Detailed explanation-3: -The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways. Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms.

Detailed explanation-4: -Lining the nasal cavity is a mucous membrane rich with blood vessels. The increased surface area and the many blood vessels enable the nose to warm and humidify incoming air quickly. Cells in the mucous membrane produce mucus and have tiny hairlike projections (cilia).

Detailed explanation-5: -In the trachea’s inner layer, you have small, hair-like structures called cilia. Cilia move in rhythm to push mucus out of your trachea so that you either expel or swallow it.
